LOOP-BEATER.

Application filed. na 15, 1914.

T 0 all whom it may concern Be it known that I, VViLLIAM BL ALL- BRIGHT, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Loop-Beaters; and I do hereby declare that the following is a full, clear, and exact de cription of the same, reference being had in the accompanying drawings, and to the numerals of reference 'marked thereon, which form a part of this specification.

The hog scraping machines now in general use utilizing flexible and semi-flexible beaters which strike the carcass and, by impact and movement thereacross, serve to dehair the same, employ a number of different types of beaters, depending upon, not only the particular kind of carcass to be operated upon, but also the particular part of a carcass which is to be dehaired.

The beater in the present invention consists of reinforced loops of fabric having strips of fabric riveted thereto and pro vided with scraper blades, and at the axis of the beater metal reinforcing plates are provided to hold the same clamped upon the beater shaft, and together with said fabric reinforcing strip act to prevent an undue bending of the beater arms.

It is an object of this invention to con struct a beater consisting of oppositely directed loops of fabric mounted upon a shaft and havingreinforcing members laid there over with bolts extending through said reinforcing members and through said loops to hold the same rigidly attached upon the shaft, and with strips of fabric riveted to the leading side of said loop and provided with scraper blades.

It is a further important object of this invention to construct a beater embracing a alurality of oppositely directed loops of fabric with the ends thereof overlapped upon one another and secured upon a shaft, and with curved metal reinforcing and clamping plates secured over said loops and bolted thereto and to the shaft on opposite sides thereof to prevent an undue bending of said loops when the scrapers secured thereon contact a carcass.

It is finally an object of this invention to construct a simple type of looped flexible beater, all the parts of which are fabric or other like material with the exception of the steel scraper blades and the metal rein- Specification of Letters Patent.

forcing members holding the beaters secured to the shaft. 7

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings: Figure 1 is a top plan view cf a beater embodying the principles of my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a section on line 33 of Fig. 2.

As shown in the drawings: 1, indicates a beater shaft, upon which one or any number of heaters may be mounted, as the case maybe, each of said beater-s comprising similar loops of fabric 2 and 3, one end of each of which lies upon the shaft, and the other end of which lies overlapped Li 3011 the end of'the opposite loop. Relatively stiff reinforcing fabric strips '7 are secured upon the overlapped ends of the respective loops 2 and 8, and are held tightly thereupon by means of curved metal reinforcing clamping members 5, which are secured in place by bolts 6, which also extend through and serve to retain said loops and reinforcing fabric strips upon the beater shaft. Secured upon the leading side of each of said loops 2 and 3, in any manner whatsoever, but preferably by rivets, and in a position to be directed opposite to the direction of rotation of the device, are short lengths or heater strips of fabric 7, which have secured thereon a plurality of metallic scraper blades 8. There is a slight difference in construction between the respective metal clamping plates 5, and this consists, as shown in the drawings, of ribs 9, formed on the outer surface of the upper clamping plate to receive the heads or nuts of the bolts 6, therein, to prevent the same turning when the bolts are taken up. Each of said clamping plates is provided with a centrally disposed reinforcing rib 10.

The operation of the device is thought to be obvious from the description. The beater shaft 1, which is mounted in a hog s raping machine, is rotated at certain rate of speed, and the scraper blades 8, on the ends of the beater strike the carcass and dehair the same, and of course, due to the flexibility of the various pieces of stiff fabric which make up the device, a. yielding scraping action takes place upon the skin of the carcass. The small plates 5, not only serve as clamps to maintain the strips of fabric assembled on the shaft, but also act to reinforce the trailing side of the beater loops when the beater is bent back, in order to prevent breaking of the fibers'of the layers of fabriclat the point of connection thereof with the shaft.

r It is very obvious that details of construction may be variedthrough a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitatedby'the prior art.

I claim as my lnventionz 1'. In a device of the class described a shaft, a beater secured thereon comprising loops of fabric, the ends thereof overlapping one another, reinforcing strips laid upon said overlapped portions, means clamping said overlapped reinforced portions to said shaft, and heater strips secured at one end to the leading sidesof said loops and having the other end projecting outwardly therer from andfdirected rearwardly of the device 'in a position directed rearWai'dly with respect to the proper direction of rotation of the device, and scraper blades secured on said 'rearwardly directed strips of fabric.

' a 8. In a'device of the class described loops secured upon a shaft, one end of each of said loops of fabric lying upon the shaft and the other overlapping the end of another loop, reinforcing fabric strips secured on said overlapped looped portions on each side of the shaft and extending outwardly behind the trailing portion of each loop, curved clamping metal reinforcing members socured over said fabric reinforcing members, bolts extending through said metal members and through said reinforcing members,

and through the fabric loops and said shaft to hold said loops and reinforcing members tightly assembled on the shaft, outwardly directed strips of fabric having one end thereofsecured upon the leading sides of each of said loops with the other end trailing freely, and metallic scraper blades secured upon said latter strips.

4. In a device of the class described the combination with loops secured upon opposite sides of a shaft, of strips of fabric having one end thereof secured to each of said loops and with the other end extending outwardly and rear 'ardly therefrom, and scraper mechanisms secured on each of said strips on the leading surface thereof.

In testimony whereof I have hereunto subscribed my name in the presence of a subscribing witness.
